[PHP-INSTALL] PHP 5.2.6 prevent apache 2.2.8 from starting up

Hi all, I have a new install of apache 2.2.8 which works fine until I enable php5 in the config. This is a fresh compile of php 5.2.6, but I had done the same with 5.2.5 right before and it was doing the same thing. The bin/php program works fine, giving me a phpinfo: phpinfo() PHP Version => 5.2

[PHP-INSTALL] Are there any tutorials on how to uninstall PHP

I'm a total newbie to all this and I want to downgrade from PHP 5.2.4 to PHP 4.3.9. Does anyone know how to do this or if there are some tutorials out there to show you how to do this. Cheers Paul
